Abstract: abstract:Theoretical investigation of characteristics of allowed dipole 2–2 transitions in beryllium isoelectronic sequence is performed applying two different theoretical methods: the relativistic many-body perturbation theory and the conguration interaction method. The data on oscillator strengths are obtained for ions with nucleus charge ranging from 4 till 29. The calculated data reveal a very good coincidence of these two methods almost for all investigated ions. The comparison of results of the present work with experimental and theoretical data of other authors for N III and Fe XXIII shows that the level of accuracy of the obtained oscillator strength values is high enough for interpretation of the experimental data as well as for modelling of the different types of plasma.
